产品概述
STEVAL-ISA076V1 is a demonstration board based on the L6924D battery charger system with integrated power switch. The L6924D device is a fully monolithic battery charger dedicated to single-cell lithium-ion polymer (Li-Pol) battery packs, and is the ideal solution for space-limited applications such as PDAs, handheld equipment, cellular phones, and digital cameras. When an external voltage-regulated wall adapter is used, the L6924D works in linear mode, and charges the battery using a constant current/constant voltage (CC/CV) profile. When a current-limited adapter is used, the device can operate in quasi-pulse mode, dramatically reducing power dissipation.
- Operating input voltage up to 12V
- Fully integrated solution with power MOSFET, reverse blocking diode, sense resistor, thermal control
- Both linear and quasi-pulse operation
- Programmable charge current both in fast charge (up to 1A) and in pre-charge mode
- Selectable 4.1V and 4.2V output voltage (±1% accuracy)
- Programmable termination current, programmable pre-charge mode voltage threshold and charge timer
- Multifunction pin for flexible charge process termination
- Status outputs to drive LEDs or host processor interface
- Battery absence detection, closed loop thermal control
- NTC or PTC thermistor interface for battery temperature monitoring and protection
